Marking out a mitred dowel joint

Step 1Check the material for knots and any defects. check the squareness of the material and select the face side and face edge. These surfaces will be the datum surfaces for all measurements and markings.

Step 2Mark 3 - 5mm of waste on the end of the material. This waste will allow for a clean end to the material as the end may not be cut exactly at 90˚. This will also remove any splintering that may have occurred while machining.

Step 3To accurately Mark the distances in for the joint use a trisquare pressed against the face edge. Place a ruler against the trisquare and mark the distance required. Use the trisquare to square the line around the work piece. Mark the width of the piece along the length of the piece to achieve the 45deg required.

Step 4 Join up the two points using a ruler. This will give the required 45deg for the joint. Use a trisquare pressed firmly against the face side to square the points around the piece and joint the points on the opposite side.

Step 5Mark the position of the dowels doe the joint. the position of the dowels will should line up exactly. The exact drilling positioning cannot be located until processing commences. Once the material is removed use a trisquare to square the markings around and then use a marking gauge set to half way to find the exact points.

Marking out completeThe marking out of the components are fully complete and ready for processing.
